It is a tool born in pandemonium before the winter word. 冬コミ前の修羅場で生まれたツールです(苦笑)
Eraser that can be erased to take the square range.

When I wear a mask, I want to erase the square greatly.
四角く範囲を取るように消去できる消しゴムです。
冬コミ前の修羅場時にたまたまできたツールですが便利かなーと思っておすそ分け。
図形ツールの長方形を線・塗りを「塗り」で、合成モードを「消去」で設定しただけですが(;^ω^)

マスク掛ける時とか、四角く大きく消去したい時などに。
